Installing Flexible Bollards with Flanged Mountings

Flexible bollards that feature a flange at their base can be installed on existing concrete surfaces using drop-in concrete anchors. Flexible bollards will bend up to 90° upon impact to reduce damage to vehicles, making them ideal for traffic applications. They can be used for lane demarcation, or creating architectural perimeters that are traffic friendly.

Drop-in anchors should only be installed in fully cured concrete that is at least 4" thick.* All measurements in this installation guide assume a bare, level concrete surface.

It is important to note that with this installation method, the bollard’s function is strictly visual and it will offer little impact resistance.

Note

To protect the finish, keep bollards in original packaging until the exact moment of installation.

Handle with care to avoid scratching or damaging bollard surfaces.

Before installation

Check for hazards

Always check for hazards such as water pipes, gas lines, and underground wiring before drilling.

Clean the surface

Dirt and debris can affect the line of sight and disrupt placement of the bollards.

Use a broom or pressure washer to clean the concrete surface prior to bollard installation.

Study the site plans

Site plans are generally created by the architect of the project.

Refer to site plans to locate and mark the precise center point of each bollard.

Create hole markings

Keep the bollard in its protective packaging. Place the bollard over each center point marking so that the bollard’s middle coincides with the center point.

Use chalk to create drill-markings for each bolt.

For secure installation, ensure there is a minimum radius** of solid concrete around each hole for the drop-in insert.

Remove the bollard.

Note: Be sure to make any necessary adjustments to the orientation now. Once drilled and installed, there is no way to rotate the bollard.

Drill the holes

Create pilot holes

Tap pilot divot holes in the center of each mark.

This will prevent the hammer drill or rotary hammer from drifting while boring the holes.

Set the depth control on the Hammer Drill (or Rotary Hammer) to 2"

If depth control is not available, mark 2" on the masonry bit.

Drill the holes

Drill a hole that has a 5/8" diameter and 2" depth.

Drill on high speed, using the hammer function if available.

Check the masonry bit often to ensure it remains free of debris.

Secure the Bollard

Clear and clean the holes

Clear the holes of all debris and/or standing water using the vacuum.

Tap the drop-in insert into each hole

With the slotted end facing down, drive the drop-in inserts (A) down until the top sits flush with the surface of the concrete.

Set the concrete insert

Insert a setting tool (B) into each hole, then hammer down.

If a proper setting tool is not available, an equivalent flat-end punch can be used.

This will cause the internal expansion plug to set the concrete insert in place.

Set the bollard over the holes

Keep the bollard in its protective packaging. Carefully set the bollard base over the installation position so that the bollard's bolt holes are directly on top of the drilled holes and concrete inserts.

When ready to install, remove the protective packaging.

Secure the bollard

Place the washers over the holes on the bollard and set the bolts into place.

Use a hex key to tighten the bolts until secure. Tighten bolts evenly in a cycle.

Care and maintenance

Reliance Foundry manufactures its products to the highest design standards to ensure their durability. In most North American environments, routine inspections and cleaning will ensure that bollards retain their aesthetic appeal. Proper care and maintenance are required to maintain the finish and ensure a full service life.
